Technology

The unrivalled power and durability of AIE lightweight rotary engines are guaranteed through the use of revolutionary new technologies that effectively eliminate drawbacks found in many other rotary engine developments.Access to the latest discoveries from leading names in rotary engine design together with advanced manufacturing capabilities enable AIE to pass on unique benefits to their customers through patented technology as detailed below.

Technology

SPARCS

AIE patented SPARCS (Self-Pressurising-Air Rotor Cooling System) is rewriting the rules in rotary engine design with the advanced ability to utilise pressurised gases from the combustion process as a medium for cooling. By means of an external heat exchanger to deliver superior heat rejection and a completely sealed engine core, SPARCS provides AIE Wankel rotary engines with longer endurance and zero oil loss for increased performance.

Compact
SPARCS

A marvel in lightweight engine development, AIE patented Liquid-Cooled Compact SPARCS (Self-Pressurising-Air Rotor Cooling System) delivers exceptional thermal balancing with surprisingly small form factor and fewer components. Utilising pressurised oil-gas mixtures for heat absorption, Compact SPARCS internal heat exchanger efficiently rejects heat from the engine core to its main liquid cooling system resulting in a longer, and lighter engine life.
